From a Japan SPF Swine Association-certified farm in Shonai, Yamagata — a fine-quality brand pork born of a clean environment and carefully selected feed.
Shonai SPF Ton: Mogamigawa Pork is a Japanese brand pork (meigara-buta) from Shonai Town, Higashi-Tagawa District, Yamagata Prefecture, managed by Mogamigawa Farm Co., Ltd. Breed / crossbreeding: Female (Landrace × Large White) × Male Duroc (LWD three-breed cross).
Shonai SPF Ton Mogamigawa Pork is a brand pork that Mogamigawa Farm Co., Ltd. — located along the Mogami River in Shonai Town, Higashi-Tagawa District, Yamagata Prefecture — has consistently produced since its founding in 1979. The farm holds certification from the Japan SPF Swine Association, and a rigorous disease prevention system is in place to prevent the introduction into the farm of five specified pathogens including Toxoplasma infection and swine dysentery. All visitors to the farm are required to shower and change into dedicated work clothes, the farm perimeter is fenced, and all incoming materials are individually disinfected — an extremely high standard of hygiene management, with almost no medication administered for treatment purposes.
The feed uses a dedicated feed incorporating Shonai-grown feed rice, with non-GMO and post-harvest-free (PHF) corn and soybean meal as the primary ingredients. Furthermore, drinking water is ionized water passed through tourmaline mineral stones — a thoroughgoing commitment to the safety of everything the pigs consume. The breed is an LWD three-breed cross (Landrace, Large White, Duroc), with a shipping age of approximately 175 days.
Through this accumulation of careful rearing, the pork develops a finely grained, moist lean, and the fat, white and light, carries a concentrated umami. With minimal characteristic pork off-odor, it is very easy to eat and active in a wide variety of dishes. Distributed through mass retailers and specialty meat retailers within Yamagata Prefecture and through furusato nozei platforms nationwide, it has long been supported by consumers seeking safe and reliable pork.
